dirtydog said:Yet the sidelights on the front of your vehicle are not bright enough for you to be seen, especially if another car has partially frosted or misted windows which at this time of the year is common. He cannot see you if you only have sidelights on - you are invisible to him. Put your headlights on - and then you can be seen.
Is this rocket science?![]()
Certainly not

Busy dual carriageway, bright enough to see the other cars and for them to see you without having headlights on. Slightly dull / drizzly rain, you can still see the other cars both in front and behind you but your rear lights are on making you more visible. Nothing wrong with that is there?
If it's dark / dusk / peeing down then headlights all the way.
